Description

A computerized adaptive psychophysical assessment in which children judge relative segment orientation to estimate visual-processing discrimination thresholds.

Components

  • Orientation discrimination task as a measure of children's visual processing: An adaptive psychophysical task used to assess visual processing in young children. Children judge whether a second bicolor segment turned clockwise or anticlockwise relative to a first segment; a three-down-one-up staircase (step size 1.0715°, starting from 10.239°) converges on the orientation discrimination threshold, computed as the mean angle difference over the middle six of ten reversals per block. The article notes "The lower the threshold, the higher the visual processing ability." Children sat 80 cm from the screen, and bicolor segments replaced pure lines to ease task demands for children.
